. LETTERING -DEVICE.

" a 7 Application filed February This invention relates to improvements in lettering devices and particularly to that kind of lettering deviceshown and described ;:f, 1 611,14O, dated inmy U. S. Letters Patent ,-December. ltth, 1926., I; j

The primary object of theinvention resides in .a lettering device in which'a series of characters are .marked out upon a disk, and f which.charactersinay be brought into registry with a suitable indicating ,,n1ark, and a letter or numeral .printed by moving a sharppointed lettering pen orpencil about the walls of the cut-out character and which device is adjust-ably mounted upon a T- square for, movement over the surfaceof the ,paper topbe printed upon.

- -Another object of I he inventionis'to em bod'y: a lettering deviceupon a T-squareso that-the sameis. alwaysmaintained in a horizontal position to assure perfect alignment of the characters as they are printed. A

Another object of the invention is'toprovide a lettering device in which the circular disk orwstencil maybe locked after the se- .,lected -characters to .be printed have been movedtothe proper adjusted position and a means whereby the characters to be printed may be; accurately spaced from the last printed .character.

-Z A further ob'ect is: to provide a lettering V device for'attachment to T-squares which is simple in construction, inexpensive of manufacture, and simple of operatlon. withthese and other-ob ects-in view-the invention resides in certainnovel construc-' -tion and combination and, arrangement of W I .Whih

wherebythe T squa'r'e may be adjusted ,to

drawing-boards of difierent .widths. "The top face of the straight edge of the T.- square may be provided :With-graduations inorder that the same maylactasaj'ruler',

in addition to a straight edge; .Aclamping .nut 16 serves to hold the'head. 12 in an adjusted'position and which is threaded on the free endof a stud which extends from the head 12. while aset screw 17 iscarried by the head and may bescrewed up. tight against theside edge of the board for hold? ing the ll-square against sliding movem'ent. A carr age 18 is slidably' mounted upon theYT-square 10 and is held-v in frictional engagement therewith by flat springs 19 interposed bet-Ween the bottom wall (if the carriage and the under edge of ,theT-square' These, springs. prevent L accidental 1 sliding movement of the carriage with respectto the T-square buti permit of the free manual sliding movementfof the'sa'me. A gauge 20 is slidably. mounted upon a" track 21 pro- "vided' 0n the' carriage IS/and" which is of, a

A bridgeor cross piece 24 connects --the arrns22 butisofl'set with respectto the I arms so'asto disposethe disk 25*inithe plane of the arms. The disk;25.is of atransparthe free end thereof The outer free ends of the arms 22 are bent atfrightangleto provide legs 28 for spacing the circularflisk and'arms irom the surface of the paper'to be printed upon. i The circular disk 25 is transparent so as tobe seen through and is divided -up;i'nto a plurality of concentric fields each of whichisprovided with characters 29 infthenature ofletters "or parts of lettersottlw alphabet and numeralsand I an ' Q which are cut 'outtherefrom so thatthe disk in realityis no more than a stencil; "The outermost field contains the larger size-char acters but which gradually diminish xincsize toward the axis of the disk. The disk 25 is supported above the paper by the 'bridgepiece 24 and by a crosspiece 30 which connects the arms 22 adjacent-their pointv of contact withjt-he straight edge of the T- square. The bridge 1 piece '30 fhas its [longitud'mal. edges recessed as at 31 to. accomm'odate and-supportthe peripheral edge of.

The] peri heral edge" of the idisk is notched 'as at 33, ona radial line withthe mounted on one of the arms 22, and'which strip is} mounted in horizontal alignment, "with'the'axis of the disk.

The operator holds v the spring strip. depressed until the character has been printed, after which it is re leased and automatically disengagesjthe disk to allow free rotation oflthe same infbring' ig the next selected charact i t printing position, a I

In operation, when it isidesired to print any particular character, the. selected char-- acter being on a radial line '36, is brought .into alignment with the vertical axis of the disk irrespective of the 'field i nwhich the character may reside. Assumeit is desired to print the Ward ;C A T in large size letters. "The'T -square is moved to a horizontal position so that the letters to be printed. may

be made on the desired plane. The disk is I i rotated to bring the letter ,Cinto -vertical alignment with the of the disk and; the
